The day Gameranger only allows for 0.93 is the day a pirate will actually bother updating game to 0.93 and post the updated files on Mininova or The Pirate Bay.
It will delay for a few days the wannabe pirates though. On the other hand, if every pirate is updated to 0.93+, we are back to square one. They will once again try to connect and look for an update on the official servers and crash them each time htey launch the game.
